Hi Jesus,
I'm having the same problem, and the triggering of this rule causes so much
noise that it's drowning out other alerts. I have added a rule like you
suggested to my local rules:
<rule id="100510" level="0" frequency="0" timeframe="45" ignore="600">
<if_matched_sid>510</if_matched_sid>
<regex>/var/lib/docker/volumes/\.*/_data/\.* is owned by root and has
written permissions to anyone</regex>
<description>Ignore rootcheck warning on world-writable docker
volumes</description>
</rule>
But it doesn't seem to have an effect. I've played with the regex,
simplifying it and even deleting it altogether, but I still can't seem to
get it working. Logtest shows the following output:
File
'/var/lib/docker/volumes/81c96e1d9b6a07710dc0ba90daccf5650efe59e213b20354bbb86f4e65929a0e/_data/path/to/static/fonts/icons/glyphicons-social-regular.eot'
is owned by root and has written permissions to anyone.
**Phase 1: Completed pre-decoding.
full event: 'File '/var/lib/docker/volumes/
81c96e1d9b6a07710dc0ba90daccf5650efe59e213b20354bbb86f4e65929a0e/_data/path/
to/static/fonts/icons/glyphicons-social-regular.eot' is owned by root and
has written permissions to anyone.'
hostname: 'ec2-12-34-56-78'
program_name: '(null)'
log: 'File '/var/lib/docker/volumes/
81c96e1d9b6a07710dc0ba90daccf5650efe59e213b20354bbb86f4e65929a0e/_data/path/
to/static/fonts/icons/glyphicons-social-regular.eot' is owned by root and
has written permissions to anyone.'
**Phase 2: Completed decoding.
No decoder matched.
I'm fairly new to OSSEC and Wazuh, so I may be missing something. Is there
anything obvious that I'm doing wrong?
Cheers!
